CLOSET-CISTERN.

SPECIFICATION forming part of Letters Patent No. 609,079, dated August16, 1898. Application filed October 16 1897- I $eria1 No. 655,373.: (Nomodel.)

To 00% whom it may concern:

Be it known that 1, JAMES P. J. CAHILL, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented a new and useful Improvement inCloset-Cisterns, of which the following is a specification.

The object of my invention is to provide a simple, efficient, durable,and inexpensive siphoning device for emptying a closet-cistern; and theespecial object of my invention is to provide a siphoning device whichwill dispense with the valve and valve-seats which have heretoforeordinarily been located below the level of the water in the cistern andwhich are liable to waste water by leakage.

To these ends my invention consists of the construction andcombinations, as hereinafter described, and more particularly pointedout in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a perspective View, partiallybroken away, of a closet-cistern constructed according to my invention;and Fig. 2 is a transverse sectional View of the siphoning. device whichI preferably employ.

A siphoning device for closet-cisterns constructed according to myinvention comprises siphon-legs, one of which maybe carried down vthrough the bottom of the tank, a starting chamber connected to saidsiphon-legs, a plunger mounted in the starting-chamloer, and means foroperating said plunger to force water from the starting-chamber intosaid siphon-legs.

The body portion of the siphoning device is preferably formed by ahollow curved Y- shaped casting. The starting-chamber is preferably of asomewhat larger diameter chamber formed from pipe-sections threaded intothe body portion I am enabled to employ similar castingsor body portionsfor forming siphoning devices of different capacities-that is to say,where the siphoning device is to be used in; a comparatively deep tankthe siphon-legs and starting-chamber would be formed of longerpipe-sections than in comparatively shallow tanks, and by means of thissingle speoialfitting or casting I am enabled to construct siphoningdevices of proper proportions and capacities for use in any desiredsituations. Referring to the drawings and in detail, A designates thetank or cistern-body portion. The tank or cistern-body portion A isnormally kept full of water, which is supplied by a ball-cock B,controlled by a float D in the ordinary manner. These parts may be ofany of the ordinary orapproved constructions.

The siphoning device which I preferably employ for emptying the tank orcistern A comprises a curved body portion or Y-coupling 10. Leading fromthe main stem of the body portion 10 is an outlet siphon-leg 11, whichmay be carried down through the bottom of the tank. The joint betweenthe tank and outlet siphon-leg 11 can be packed Connected to one ofthebranchesof the Connected to the other branch of the body 7 portion 10 isa starting-chamber 13.

The starting-chamber 13 is preferably of somewhat larger diameter thanthe siphonlegs "lOfand 11, so that the body of water forced from saidstarting-chamber into the siphon, as hereinafter described, will beamply sufficient to insure the siphon startingin action.

The starting-chamber 13 is perforated at its lower end, as at 14, andextends nearly to the bottom of the tank.

Mounted in the starting-chamber 13 is a plunger 15, which is carried bya rod or wire 17, preferably extendingup through a small gland orstuffing-box 16 in the bodyportion 10. The rod or wire 17 is connectedto an operating-lever 19 by means of a chain 21. The operating-lever 19is pivoted in a bracket 18 and is controlled by a pull-cord 20 in theordinary manner. By means of this construction it will be seen that whenthe lever 19 is operated by the cord 20 theplunger 15 will be raised,forcing a body of water from the starting-chamber 13 into the siphon.This will start the siphon into action, and water will continue to flowthrough the siphon until the tank or cistern has been substantiallyemptied.

The especial advantage of a closet-cistern siphoning device as thusconstructed resides in the fact that all valve-seats and pack-joints,which are liable to leak, are dispensed with. The construction of thisform of siphoning device does not require accurate work or fitting. Forexample, the plunger 15 can fitquite loosely within the starting-chamber14 without interfering materially with the efficiency of the device.

I am aware that changes may be made in the construction of siphoningdevices for closet-cisterns without departing from the scope of myinvention as expressed in the claims. For example,in practiceIfrequently dispense with the gland or stuffing-box 16. I do not wish,therefore, to be limited to the form which I have shown and described;but

What I do claim, and desire to secure by Letters Patent of the UnitedStates, is

1. As an article of manufacture, a siphoning device for closet-cisterns,comprising a curved, Y-shaped body portion, an outlet siphon-legconnected to the stem of the Y-body portion, an inlet siphon-leg, and astartingchamber of largerdiameter than the siphonlegs connecting to thebranches of the Y- shaped body portion respectively, and means forforcing water from the starting-chamber into the siphon-legs, the bodyportion being shaped to form a curved, gradually-tapering passage forconcentrating and directing the flow of water from the starting-chamberinto the outlet siphon-leg, substantially as described.

2. In a device of the class described, the combination of a tank A, afloat-controlled ball-cock B for normally keeping said tank full, and asiphoning device comprising a curved Y-shaped body portion or casting10, an outlet siphon-leg 11 connected to the stem thereof, an inletsiphon-leg 12, and a starting-chamber 13 of larger diameter than thesiphon-legs connecting to the branches of the Y-shaped body portionrespectively,said body portion being adapted to form a curved,gradually-tapering passage for concentrating and directing the flow ofwater from the startingchamber into the outlet siphon-leg, saidsiphon-legs and starting-chamber being formed by pipe-sections threadedinto the body portion, a plunger 15 mounted in the startingchamber, anoperating-lever 19, and connections from the operating-lever for raisingthe plunger, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

JAMES P. J. CAHILL.
